Abstract: A method is provided for detecting presence and absence of a creature. The method includes, receiving an input signal from a radiation sensor; applying a first low-pass filter to the received input signal with a first time constant and generating a first filter output; applying a second low-pass filter to the received input signal with a second time constant and generating a second filter output. The method also includes determining a presence of a creature by comparing a slope of the first filter output to a predetermined value; and determining an absence of the creature based on further processing. A corresponding device for detecting presence and absence of a creature is also provided.

Abstract: A computing device may be configured to display content based on the content type, and may include a display, a memory configured to store instructions, and at least one processor coupled to the display and the memory. The at least one processor may be configured to execute instructions stored in the memory to determine content information associated with a display mode, receive input display data associated with the content information, select a display mode based upon the determined content information, generate output display data based on the selected display mode and the input display data, and provide the output display data to the display based on the selected display mode. For example, the device may select interlace mode as a default mode for display, and may select progressive mode when the determined content information indicates the input display data is high quality video data.
